Last year I bought my first red dot (yeah, at age 45!
Somehow just never tried one ever before). The one I bought was a PA Classic Red Dot very similar to the one you linked. Like you I'm more low-speed, high-drag.
The sight has worked very well. I can't say if it will last for five years but so far so good.
I did recently replace it with a HOLOSUN RDS that cost twice as much. Still not an Aimpoint but very nice. PA imports HOLOSUN, btw. The reason I upgraded was that my older PA didn't have an auto-on, just an auto-off. The HOLOSUN wakes instantly when moved and has been reliable.
I don't suppose I'd choose any of the Chinese RDSs as a "go to war" optic. But I'm not a soldier. I do keep the HOLOSUN on my home defense gun but it cowitnesses with the iron sights (okay, the
plastic sights!
) so I'd just put the front sight on the bad guy.
We are maybe in the same boat. I wanted an Aimpoint but I have astigmatism, and having never tried any RDS I didn't want to spend $400 without knowing if I could use a RDS. I do get a little bloom/smear from the dot- that is astigmatism, not an issue with the sight. But it doesn't impede my ability to get fast accurate hits with it, and it's not a lot of artifacts.
Eventually I will still probably get the Aimpoint for my serious defensive gun, but I think you'll be pretty pleased with the Primary Arms sight for range use or hunting/varmint shooting.
